500W to 6kW MPPT battery charge solar power system

Feature

1) Solar power system for residence

2) MPPT charge controller, improve the PV efficiency.

3) Low standby loss and good performance for inductive load, like motor, air-conditional.

4) Solar first while the gird backup / the grid first while solar backup, 2 modes are switchable.

Work mode 1 (Solar first)

1) When the solar power is enough, it supply to the loads directly, and save the surplus to battery bank.

2) When the solar power is weak, it supply to the loads with the battery bank together.

3) When there is no solar power, the battery bank supply to the loads.

4) When the battery is insufficient, the system will switch to the grid bypass.

Work mode 2 (The grid first)

1) When the grid power is OK, the system power the loads from the grid power. The battery bank is as the backup power, the solar panels keep the battery full charged.

2) When the grid power blackouts , the system swith to the solar and battery mode.

3) When the grid power recovers, the system will switch to the grid power automatically.
